Built by people who write estimates for a living
Not a generic SaaS studio guessing what a service business needs. MCR System came out of one hood cleaning company's actual paperwork problem, and it's still shaped by that today.
Where it started
MCR System started as an internal tool for D&E Hood Cleaning, a real commercial kitchen exhaust cleaning company. Estimates got written on paper or typed into a text thread, approvals got chased by phone, and it was too easy for a signed job to turn into an invoice nobody remembered to send.
The tool that fixed that for one hood cleaning crew is the same estimate-to-invoice engine you're looking at now — rebuilt so any service business could run on it, not just the one it was built for first. It's why the product still talks like a field crew instead of a SaaS pitch deck: that's where the requirements actually came from.
What stayed the same as it grew
The product now serves every trade in the list below, not just the one it started with — but a few decisions never moved.
Your money is yours
Online payments run through your own Stripe Connect account. When a client pays an invoice, it lands in your bank — never ours, and we never take a cut of it.
Free means free
The Free plan isn't a disguised trial. It's capped, not timed — no credit card to start, and no countdown pushing you toward a plan you don't need yet.
Every business is walled off
Your data sits behind organization-level access rules enforced by the database itself, not just app code. A September 2026 security review — including live attempts to break that isolation — found no way for one business to reach another's records.
A real person answers
We're a small team, not a ticket queue. Support requests go to people who work on the product, not a call center reading from a script.
One estimate-to-invoice engine, eleven trades, no hierarchy

How we operate
MCR System is built and supported by a small team, not a large company with a call center. When you email us or open a support ticket, a real person who works on the product reads it and replies.
We'd rather tell you plainly when something isn't built yet than promise a feature we haven't shipped — you'll see that same directness in the FAQ and in how the product is priced. The same standard applies to accessibility: our accessibility statement says exactly what's in place today and what still isn't, instead of a blanket compliance claim.
Curious how we handle your data, or what happens when you cancel? That's covered in the Privacy Policy and Terms of Service.
